A new study shows that tiny gold particles could circumvent damaged photoreceptors in patients with macular degeneration and ...

When targeted with infrared lasers, the microscopic gold pieces reproduce ... These photoreceptors come in the form of "cone" cells responsible for our perception of color, and "rod" cells ...

Next, while you are looking at a target, the Oz system uses infrared light to track ... precise bursts of visible laser light to thousands of M cones, one at a time. This cell-by-cell control ...

Thus, the Berkeley team set out to understand and overcome this limitation by mapping a part of the person's retina to find out the positions of the M cones. A laser was used to scan the retina ...

Published in Nature, the research is the first demonstration of an on-chip, picosecond, mid-infrared laser pulse generator that requires no external components to operate. The device can make what ...

When targeted with infrared lasers, the microscopic gold pieces reproduce electrical ... These photoreceptors come in the form of "cone" cells responsible for our perception of color, and "rod" cells ...
